An equation has an equal = sign whereas an expression does not.

An expression simply contains no equals sign. This is an expression: 2x + 4y + 3 An equation contains an equals sign. This is an equation: 2x + 4y + 3 = 0

An algebraic expression doesn't have an equal sign (e.g. 4x+7) whereas an algebraic equation does (e.g. 4x+7=19). 4x=19-7 4x=12 x=12/4 x=3

Equation: x+3=3+x (notice the equal sign: equal; equation)Expression: x+3 (notice no equal sign)

an algebraic equation that describes a relationship between several variables is called a?

A polynomial is always going to be an algebraic expression, but an algebraic expression doesn't always have to be a polynomial. An algebraic expression is an expression with a variable in it, and a polynomial is an expression with multiple terms with variables in it.

Algebraic expressions use letters as variables to represent numbers. Ex. 5c-(2+x) x=2 c=12 Numerical expressions use numbers only. Ex. 12+(2-7)

The differnce between a verbal model and a algebraic model is that a verbal model is an equation written in words and a algebraic model is solving the equation from the verbal model.
